This evaluation undertaken for the Ministry of Health to provide a nationwide snapshot of the acceptability of Drinking-water Assistance Programme processes, from the perspective of drinking-water suppliers who have applied for funds from the Capital Assistance Programme (CAP).
This report was prepared for the Ministry of Health to provide drinking-water suppliers with information to guide them through the identification of a water supply’s Priority 2 determinands using a qualitative assessment of the likelihood of them being present in the water supply.
This report was prepared for the Ministry of Health to examine in detail how demographic changes in New Zealand may affect water supplies and what consequences for public health these changes may have.
This report was prepared for the Ministry of Health to review the hydrogeological setting in the Darfield-Kirwee area, assess the vulnerability of the aquifer underlying the central Canterbury Plains to water quality impacts from the septic tank clusters, and analyse the functionality of Selwyn District Council’s (SDC’s) groundwater quality monitoring well network.
This guide was prepared for the Ministry of Health to provide tools to help water suppliers and DWAs in the identification of Priority 2 and Priority 3 determinands (except cyanotoxins) using a qualitative assessment of the likelihood of them being present in the water supply.

The survey reported here was undertaken to provide the Ministry of Health with an update of information on arsenic and nitrate in New Zealand networked drinking water supplies because of changes in our understanding of risk factors leading to arsenic in water supplies, and land-use changes possibly influencing nitrate concentrations.
This report was prepared for the Ministry of Health to consolidate New Zealand data on emerging organic contaminants in watsewater and the receiving environment, and assess the risks to public health of this.
This report was undertaken for the Ministry of Health to review data from the annual survey of drinking water quality to see if there was evidence that maintaining a chlorine residual could overcome occasional E. coli transgressions, and evidence of the cause of these transgressions.
